C Program to print Lower case English Alphabets in reverse

Description

Output:
z y x w v u t s r q p o n m l k j i h g f e d c b a

Solution

#include<stdio.h>
int main()
{
	int i;
	for(i='Z';i>='A';i--)
	{
		printf("%c",i);
	}
	return 0;
}

Explanation

Instruction(s) inside the for block{} are executed repeatedly till  the second expression is true.

Here i is initialized to z(122) and decremented by 1 for each iteration, instructions inside the for block are executed unless i becomes less than a(97). so value of i will be printed as character like z,y,x...a using printf statement and format specifier %c.
